FAQ

Why does TLS warn about certificates?

The demo uses a self-signed certificate for local learning. Browsers and clients will warn because it is not signed by a trusted CA.

Why are there native examples inside the package?

The examples are included so the wheel can ship a complete learning kit. The pybind11 extension lives inside the main package under hello_ext.

Can I run the examples without installing?

Yes. You can run modules directly from the source tree, for example:

python -m new_year_2026.tcp_tls.tcp_server
